Explore the hidden world of magnetic fields through the powerful idea of lines of force, and see how this view unites magnetism, electricity, and induction.
This classic text presents a clear, beginner‑friendly account that builds from first principles, using diagrams and qualitative explanations rather than heavy math. A translator’s note emphasizes the aim: to make the new theory accessible, with practical demonstrations and explanations grounded in experiment.
Written as an introduction for students and curious readers alike, the book foregrounds the field surrounding magnets and currents. It shows how energy concepts and field symmetry illuminate the behavior of magnetic and electric phenomena, and it guides readers from basic ideas to wider applications, including induction and the operation of motors and machines. The work blends theory with laboratory practice, offering simple experiments that illustrate the core concepts.
- Defined, step‑by‑step development of lines of force and their role in magnetism and electro‑magnetism
- Accessible discussion of energy in magnetic fields and how it relates to practical devices
- Qualitative treatment of induction, oscillations, and related phenomena with real‑world applications
- Illustrative experiments and diagrams that help visualize abstract concepts
Ideal for readers of science textbooks, early physics students, and anyone curious about how magnetic and electric forces arise and interact.
